Abstract: Systems, apparatuses, and methods for network-managed direct device to device communications are provided. Certain aspects of the disclosure involve receiving, at a first UE, UE1 configuration information for an inter-device session (IDS) between the first UE and a second UE, UE1 configuration information including a radio network identifier. A control message configured with the radio network identifier and a radio resource identifier for the IDS can be received. The radio resource identifier corresponds to a radio resource for transmitting data directly from the first UE to the second UE during the IDS.

Abstract: An electronic device encodes traffic data as a collection of codes. The electronic device sends the codes in random access resources or shared transmission resources over a wireless link to a wireless access network node, the codes providing an encoded representation of the traffic data.

Abstract: System and methods for scheduling OFDM frames are provided. Each packet is assigned to a frame bucket, this amounting to a temporary decision of when to transmit the packet. Each packet is marked with one or more metrics. The metrics are used to sort packets and make scheduling decisions. Packets are analyzed to determine their suitability for MIMO transmission.

Abstract: Methods and network elements partitioning at least a subset of contention based resources for random access attempts into a plurality of partitions, wherein each of said plurality of partitions is associated with at least one precondition governing selection of a partition, the precondition being derived from at least one of: source of causation for the random access attempt, a device state, a device event, a device group, a traffic event, a traffic class, or an application characteristic, and wherein each of said plurality of partitions is further associated with at least one configuration parameter; and communicating configuration parameters for the plurality of partitions and preconditions governing partition usage to at least one of a plurality of user equipments. Also, methods, devices and network elements for communicating on partitions.

Abstract: A system and method for communication in a wireless communication network are disclosed. One embodiment of the system includes an overlay access node that supports Almost Blank Subframes (ABSs). The overlay access node, such as macro eNB, can receive measurement results from one or more user equipments, including macro user equipments (UEs) and/or pico (UEs), either directly or via an underlay access node, such as a pico eNB. The macro eNB can determine a set of macro UEs that are sufficiently close to the macro eNB for transmission during ABSs with a low transmission power or beamforming without significant interference to the pico UEs. This scheme improves the throughput of transmission between the macro eNB and macro UEs while reducing interference to the pico UEs.

Abstract: The present invention provides a scheduling technique that allows individual nodes in a wireless communication network to independently determine their own communication schedules. The communication nodes in the wireless communication network are associated with one or more compatible communication nodes through substantially non-contending communication links, wherein the communication links within a group of compatible communication nodes are substantially non-interfering. Each node will exchange scheduling information with the various compatible communication nodes, and determine the communication schedule for future communications with those compatible communication nodes. This communication schedule may dictate when information is received from or sent to a compatible communication node during a given transmission opportunity.

Abstract: In a wireless network, a lowest cost path from a source node to a target node is selected from a plurality of potential paths. The source node sums costs for the links of each potential path. For each link, these costs include a cost of interference, dependent on a number of nodes affected by a signal sent via the respective link. The link costs can also include a cost of transmission, dependent upon a data rate for the respective link, and a cost of coordination for transmissions with other nodes of the network.
